To all whom it may concern: y

Be it known that 1, JOHNW.` STIEFEL., a citizen `of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certainnew and useful lmprovements in Radiators `forAutospecilication. y

My invention relates to improvements in radiators for automobiles oi"the'water circulating type, its object `beingto dispense with thewater-tubes forming part of the ordinary radiator, and to otherwisecheapen and simplify the construction and make the same more effective.y y

' More particularly the invention consists in the construction,combination, and arrangement of parts hereinafter described and claimed.y v

lin the accompanying drawings showing one embodiment of the invention,

Figure 1 is a perspective view of my im-` proved radiator shown partlybroken away.

Fig. *2 is a vertical section through the bottom portion of theradiator, showing it in inclined position assumed when the car is movingup an inclination, and

Fig. `3 is a detail view ot the top partei? one of .the screens Aand -anadjacent wall forming part of the radiator.

Referring to the accompanying drawings,

A represents the side walls ofmyimproved radiator, the lower ends 2 ofsaid walls being bent outwardly/pand secured as by rivets 3 to theautomobile chassis 4:. The front edges oit' the side walls are connectedby` a plurality of plates 5 spaced` apart and directed downwardlyrelative to the radiator. The rear edges of the side walls A :aresimilarly connected by a plurality ot plates @spaced apart and directedupwardlyrelative tothe radiator. Constituting the bottom of the radiatoris a tankportion 7 connected by a tube 8 with the waterl circulatingsystem. rlFhe radiator bottom 7 is formed with an oblique division wall9` connecting y the front and back oi' said bottom and being directeddownwardly toward the rear. A Wall 10 extends upwardly :tromthefgtrontend of the wall 9 to the top ot the back wall of the radiator bottom.The walls 9 and 10 are formed with perforations 11 and 12 respectivelyfor the purpose hereinafter pointed out. rlhe front wall of the radiatorbottom extends upwardly beyond the adjacent ends. of the division wallsas shown best in Fig. 2. f.

A `plurality of vertically disposed openn work partitions 13 aresupported upon the wall 10. rl`he partitions 13 are spaced, apart asshown in Fig. 1 and extend upwardly` between the plates and 6 to theunder side of the hollow radiator top 14. The bottom wall 15 oit theradiator top is formed with openings 16 directly above theupper ends ofthe partitions 13. The upper ends 17 ot the partitions 13 are preferablydoubled upon themselves underneath the openings 16. rllhe tubes 8 and 18form opposite connections for the radiator with the water dis-`tributing system. rlhe radiator top is 'formed with the usual fillinginlet tube 19 to per-` mit lling of the radiator. y ln` lilling :for usethe water .is poured through the inlet tube to supply the radiator inthe ordinary way. The` waterwhen it -is not @being circulated standsatthe bottom of the radiator below the open work or screen partitionsand also below the wall9 or approximately on the level with holes 11 asshown in Fig. 2. When. water is beinglcirculated as by the water pumpordinarily used it will pass from the tube 18 to the radiator top,thence passing through the openings 15 onto the screen partitions. Thewater `will thence travel down the partitions and pass through openings`12 in theplate 10 onto the plate` 9, `and willthen pass through opening1l to the space below `said plate 9. As the C2141t carrying the:radiator moves rapidlyforu ward through space,the inertia in the wateras it flows upon the plate 10 is not fully overcome,` therebycausing alarge portion of it to flow rearwardly. For the purpose of arresting atoo rapid rearward `flow of the water.` and thereby avoid: splashing`ag'gainst `the rear `wall of the ltankportion 7.,

spread film-like over the plate 10, thereby delaying its descent andiiow through the lower of the holes 12, thereby further cooling it. Theupper holes 12 near the rear wall, catch any water that may find its wayto that uppermost portion of the plate 10, when the car is exceeding anormal rate of speed. The function of the lower plate 9 is identicalwith that of plate l0, except that it is operative in abrupt stops andbackward driving of the-car. The turned or thickened upper ends 17 ofthe partitions assist in guiding the water as it passes from theopenings 16 onto the body of the partitions. By having the walls 9 and10 inclined as above explained, the water from the partitions runs morefreely into the hollow radiator bottom, and also the main body of wateris forced back and forth through the holes l1 in said wall 9 by themotion of the car.

The plates 5 being directed downwardly from the open front' of theradiator to form deflector plates prevent water, etc., being blown intothe interior of the radiator. The plates 6 being directed upwardly atthe open back of the radiator tend to direct any water that may be blownagainst them from thescreen partitions back into the interior ofthe'radiator, conserving the supply of water.

' The spaced walls 5 and 6, while having the advantages above noted, atthe same time allow the circulation of air through the radiator toassist in the cooling action of the water.

By my improved construction I avoid the objections ofthe ordinarytubular construction of radiator securing a construction which isparticularly 'easy to keep` from leaking' and very cheap and simple. Myconstruction is particularly adaptedv for winter use as there is not thedanger of freezing that there isin the ordinary tubular construction. InFig. 2 the radiator is shown tiltedto a position with the car on aninchne, showing how the water stays almost wholly vbelow the top vwalll0, the water having'access to the space between the plates 9 and IO,solely through the holes 11, which are at the lowermost edge of theplate l9. The car will travel overv short steep grades, before thecomparativelylarge` bodyof water will have had .time to flow throughvthe holes 11, thereby controlling the waterv in the tank'to preventobstruction ofthe spaces above wherein the cooled water is descending. vI claim radiatorA of.` the class described' comprising side wallsconnected. across the front and baclrby spaced inclined dee'ctor plates,saiddeflector plates 5 being inclined downwardly and'plates 6 upwardlyrelative to the radiator and outwardly from said front and back, ahollow radiator top supported by said side walls, a hollow radiatorbottom and a plurality of open-work vertically disposed partitionssupported in spaced relationship above said bottom, and extendingupwardly to said radiator top.
